l To all whom it'may concern:

F scribes the axle 1.

Be it known that I, PA-RLEY'D. ,Roo'r, a citizen of the United States, residing at North Springfield, in the county of Windsor and State of Vermont, have invented a new and useful Lubricating-Hub, ofywhich the;

followin is a specification.

One ohject of the present invention is to provide ahub structure for vehicles, which will operate with minimum friction.

A further object ofthe invention is'to provide novel means for lubricating the hub.

The invention aiins further to provide;

leaking out of t e hub.

prove genera vehicfe wheel, and to novel means for reventing a lubricant from hub at either end of the,

Another oby'ect of the invention is to imly, the hub construction of, a

provide novel means 1 for assembling the hub with the spindle of;

the vehicle axle.

With the foregoing and other objectsin proceeds, the invention resides in the combi nation and arrangement of parts and in the View, which will appear as the description details of construction hereinafter described and claimed, it being understood that changes in the recise embodiment of invention herein disc osed can be made within the scope of what. is claimed without departing from the spirit of the invention.

In the drawihgs-Figure 1 shows the invention in longitudinal section; Fig. 2 is a transversesect-ion on the line 2-2 of Fig. 1; Fig. 3'is a transverse section on the line 3-3 of Fig. 1 5 and Fig. 4 is a fragmental longitudinal section showing a slight modifica- 'tion in the invention. r

I In the drawings, the axle is denoted by the numeral 1, the same having a spindle 2 terminated in a threaded tip 3. The hub is denoted by the numeral 4 and is provided at its inner end with a projecting flange 5 which is received in a recess 6 whichciroum- Interposed between the end face of the axle 1 and'the inner end face of'the' hub 4 is a washer 7, and at this point it, may be stated that anydesired nlunlwrof WilF'lWIS may be employed. It desired,'a packing ring 7 may be interposed between the pe riphery of the washer 7 and the flange 5. In

the inner face of the washer 7 and relatively near to ihe spindle 2 there is an annular recess 8 located'opposite to anannular recess 9 formed in the inner end face of the hub 4. Extended longitudinally of the hub 4 and communicating with the recess 9 is-a duct 10 which, in its turn, communicates with a radial oil passage 11 in the hub 4, the oil passage 11 being equipped at its extremity with a closure 12 which may be in the form of a.

threaded plug. In theinner end face of the hub 4 there is formed a ball race 14, containing balls 15. Beyond the ball race 14 there is formedin the washer 7,. an annular recess 16 communicating with another re cess 17 formed in the inner end face -of the hub 4. Located beyond the rccesses'16 and 17 and formed in the inner end face of the hub 4 is a ball race 18, containing balls 19. Surrounding the inner end of the indie 2 and received within a recess in the ub 4 1s a metallic casing 20, having, at its outer end, a flange 21 which projectstow'ard the The inventionvfurther includes a ca. 25 having a flange which is threaded as indicated at 26 upon a flange 27 formed at the outer end of the hub 4. Located within the flange 27 is a closure plate 28 having a boss 29 into which thetip 3 of the-spindle'2 .is threaded. Abutting against the closure the usual, superficial oil-duct 24.

plate 28 isa washer .,30. Any number of washers 30may be provided. A packing 31.

In the outer endface of'the hub 4 is formed a ball race 34,\containing. balls 35. Located outwardly of the ball race 34 and formed in the washer 30, is an annular re- .lcess36 communicating with the recess 37 in the outer end face of the hub 4. L0-
